Abstract (en)

An improvement of a homopole type AC generator which is of homopole type arrangement and is adapted to generate alternating current (AC) depending upon interlinkaging operation of magnetic fluxes comprising a rotor magnet (25a, 25b) rotatable by a rotational force from outside, a yoke (11a, 11b, 11c, 11d) through which magnetic fluxes flow from the N pole of the rotor magnet to the S pole and forms a part of a magnetic circuit, and generating coils (22a, 22b) provided at positions interlinking with the magnetic circuit, wherein a magnetic circuit connecting two rotary pole pieces (26a, 26b) which are provided on a rotary drive shaft (24) at both sides of the rotor magnet is disconnected to eliminate a harmful magnetic circuit opposing the action of generation.
